This invention relates toda flush 'tank inl' let valve or what iscommonly know'n as a ball cock, and one-object ofthe invention is torovide a valve'of this character em- -1 5 bo ying novel and improvedfeatures of construction so that the valve may be economically'manufactured, easily installed and will be reliable and durable inopera' tion.

comprised of a minimum number of simple parts and which c an beinstalled in any of the known t' pes of flush tanks without alz terationot t e usual inlet pipe connections. i lFurther objects are to providesuch a valve v embodying novel and improved features. of constructionwhereby the valve and its casingv may be located out of the water and vin such position Within the tank as not to interfere with vthe usualflush valve mechanism and so that the inlet valve n iay be convenientlyadjustedor repaired; to th'us pro- .videv a novel' and' improved valvecasing, which can be-eonoinically cast, and to ob-- tain other resultsand advantages as may be brought out by the' following description.

Referring to the accompanying drawings, in which'corresponding 'and likeparts are designated throughout the several views by the same referencecharacters,

Figure 1 is'a fragmentary sectional view y through a Hush tank showininside elevasi said-fitting having a fiange 2 adjacent one ."'end'thereof between which/'and the 'inside ofthe bottom wall of the flush`tank is disposed'a '.the tank so as to clamp thev tting within .theopening A -fitting 1- is provided, with a sli @joint-forother'suitablepipe 'connection 5 or goining f the water supply-"pi ewiththe tting 1.

the fitting is arranged within a' lushtank diverges .from the side ofthe4 tank.y lIn this connection, it will be remembered that the waterinlet opening of the Hush t'ank `is usually arranged in one corner offthe tank dueto the necessity of arranging the inlet valve mechanism sothat it will not inter fere'with the outlet orlushvalvefmechanismfwhichis ordinarily placed in the center of the tank.A straight pipe y7 has one end threaded in the opening 6 and has itsother end threaded into an inletopening 8 of a horizontal inlet valvecasing f The valve casing 9 is formed with an inlet chamber- 10 and avalve chamber 11 which are separated by a transverse partiti0n,or Wall12 having an opening 13 therein. Said chambers 10 and 11 are insubstantially axial a'linement and at an acute'angle to the axis'of theinlet opening, and the side of the partition 12 in the valve chamber 11is formed with 'a valve seat 14'. An outlet opening 15 for the valvecasing 9 is formed at one side of the valve chamber y11 andsubstantially arallel and in the same plane with the ii'det opening 8.An opening 16 is provided inthe valve casing 9 substantially The axes ofthe chambers 10 and 11, and openings 8, 15 and 16 are all in the sameplane.\ Said opening 16 is threaded and has fitted therein a valve stem'17. at the inner end of which is arranged a valvehead 18 to cooperatewith`the valve seat 14. The exterior of the valve casing surrounding theopening 16' isth'readed at 19 to receive a land cap 20 between which andthe end o .the casing is arranged a packing ring 21. The gland ca 20 hasa aas passes a Outwardly o f the gland capy 20 the valve. d i

shank 23 is corrugated or otherwise provided witha plurality of ribs orgrooves 24 which extend to the end of the shank, and the 'shank isprovidedin'its end with a central threaded' opening 26. ,A ball or oat Cfor operating.- the valve is arranged at one end of a rod D, the otherend of whichis secured as by screw vthreads tof a collar 27 which has acentral corrugated opening '28 ,to iit vthe corrugated lend 24 STliisconstruction so'V ar described is-old and Ifln'olelaixii 'to n 'oveltthereon is made.v

corrugated end Yof the shank and is held of the shank 23 of the valvestem. The m.

thereon by means of a set screw 29 screwed into the opening 26, a washer30 preferably being interposed between the head of the screw and thecollar.

With this construction, it will be observed that rotation of the valvestem will move the stem longitudinally and seat andunseatthe valve head18` on and from the valve seat 14 so'as to close and open the port- 13,

respectively, and rotation of the valve stem is caused by the ball Cresting upon the surface of the water in the lus'h tank, a rise inthelevel of the water closing the `valve and a fall in the level openingthe- ,of the tank, and in operation of lthe valve valve. The ball C, maybe adjusted rela# tively to .the valve stem to cause proper opening andclosing of the valve by changing the relation ofthe ballto the stemvthrough adjustment of the collar 27 on the corrugated end 24 of theshank 23.

A n outletpipe 31 is fitted into the opening 15 of the valve casing 9'and leads downwardly toa point spaced from the bottom mechanism, whenthe valve is open water will iiow inwardly through the pipe fitting 1,inlet pipe 7, inlet chamber 10, port 13,J

vvalve chambery 11 andoutlet pipe' 31 into the tank. A refill orrelatively small discharge pipe 33 is connected to the valve chamber 11for supplying `water for the afterflow or water seal following theflushing The valve casing 9 with the co-axial inlet chamber and valvechamber 10 and 11, respectively, the co-aXal valve stem 17, and thelateral inclined parallel inlet opening and outlet opening 8 and 15Irespectively, is simple and relatively inexpensive to man-A ufacture,and combined with the inlet pipe titting 1 having the inclined opening6,

enables a straight pipe 7 to be used for locatdetails may be modifiedandl changed by those skilled in the art without departing from vthespirit or scope of the invention.

Therefore, I do not desire to be understood vas limiting myself exceptas required by the y following claims when construed in the light of theprior art.

Having thus described the invention, what I claim is:

1. A flush tanky valve mechanism comprising a pipe coupling to be fittedin an opening in the bottom of a flush tank and having an openingarranged at an angleto the axis of the coupling, a valve casing hav-ving an ,inlet opening inclined correspondingly to said opening in saidcoupling and an outlet opening, a valve in said casing for controllingcommunication `between said` inlet .Opening and said outlet opening, anda pipe having its ends connected to said opening in said coupling.. andsaid inlet openingof the valve casing, respectively, whereby the inletof said valve casing is'oii'set from said coupling to facilitatemounting saidmechanism in a tank and adaptingsaid pipe to l be easilyand quickly replaced.

2. The combination with a flush tank having an opening in its bottom, ofa pipe coupling fitted in said opening and having an opening in itsinner end disposed at an obtuse angle to the axis of said coupling anddiverging from the adjacent side of said tank, a vhorizontal valvecasing having an inlet opening in its under side inclinedcorrespondingly to said opening insaid coupling, said casing alsohaving` an outlet, a valve in said casing for vcontrollin communicationbetween said inlet and said outletl and having a. horizontallyprojecting rotatable stem, an arm-having one end connected to said stem,a float connected to the other end of' said arm whereby rising andfalling of said iioat Arotates said stem, and a pipe, having one endconnected tosaid inlet opening and the other end connected to said',opening in said coupling so that said pipe is vinclined. with respect tothe sides of sald tank and said -valve'casing o'set with re- 100 specttosaid couplingrto'facilitate mountin the valve casing 1n a tank andadapting sai pipe to be easil:r and uickl re laced.
